The AirTAC GFR600C20ALJC3WT AirTAC Filter Regulator NPT3/4 is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600C20ALJC3WT is a size 600 filter regulator: water and particulate removal plus pressure regulation combined in a single body, with a 3/4 in NPT port. This configuration carries the W fine filtration grade (5 um element, in place of the standard 40 um), an automatic drain that ejects collected condensate without manual attention, the low-pressure regulator type, and an external round pressure gauge with a bar scale. At size 600 the bowl is aluminium alloy, and this unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and is offered with a choice of drain type, filtration grade, gauge style and scale, thread form (PT standard; G and NPT as order options) and bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Installed at a 3/4 in main drop feeding carton sealers, case erectors and labelers, this unit filters water and debris from the shop air and holds a steady low regulated supply, while the automatic drain keeps condensate out of the downstream valves.
Mounted ahead of clamps, tool changers and actuator circuits on a CNC machining centre, the 5 um element protects sensitive directional valves from particulate carryover and the regulator keeps actuator pressure stable through the shift.
On a skid supplying pneumatic quarter-turn actuators, the low-pressure regulator type suits circuits run below standard line pressure, and the bar-scale gauge gives operators a direct local reading at the panel.
Size 600 with a 3/4 in NPT port is the large-flow step of the GFR range; step up or down through sizes 200/300/400/600 as your line size and air demand require. Because flow is published as curves and not as a single rated figure, ask us to check the curve against your application before you order. This unit is already specified with the choices that matter: 5 um filtration (the W grade, instead of the 40 um standard), an automatic drain (instead of manual or the differential-pressure default), the low-pressure regulator type, and a round gauge reading in bar. If you would rather have the embedded square gauge, a different scale (MPa or psi), a bracket, or PT or G thread instead of NPT, those are catalogue options on the same family - tell us and we will confirm the matching code.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Send us your inlet pressure and required downstream demand and we will confirm the sizing from the datasheet curve before you order.
The automatic drain ejects collected condensate on its own, so the bowl does not need periodic manual draining the way the manual-drain option does - useful where the unit sits in an inaccessible spot. The W grade fits a 5 um element instead of the 40 um standard, giving finer particulate removal for downstream valves and instruments.
